Lame Patent No. 62,612, dated March 5, 18 67.

IMPROVED METHOD or museums AND creme YARNS, GLOTHS, AND OTHER TEXTILE FABRICS.

(lllgt some reform in in tigers gone are: in making part of ilge am.

Be it known that we, Isaac 0. Corner, of th city of Buffalo, and ALBERT Hssrmcs; of the, city of Rochester, in the State of New York, have invented'a new and improved Method of Bleaching and DyeingOloths, Yards, and other Textile Fabrics; and we hereby declare that the following is fa full and exact description thereof.

Our invention consists in subjecting the fabrics or materials to be bleached or dyed to the action of the bleaching or dyeing liquors or solutions, .by the use of hydraulic or hydro-dynamic and pneumatic pressure in manner following: We employ a closed tub or cylinder, with a suitable man-hole, oraperture in the surface, through which to put the cloths or fabrics to be operated upon, with a cover suitably arranged for screwing 0r fastening on,"so as to prevent the escape oi air and of the bleaching or dyeing liquors.- The cloths or fabrics are inserted into the tub, vessel, or cylinder, and the cover properly secured. We then employ a force-pump working with a pipe or hose inserted into the vessel or cylinder through a hollow journal, and thereby force, by hydraulic or hydro-dynamic pressure, a sufficient-quantity of the bleaching or dyeing liquors into the vessel or cylinder to fill the same, and by the application of sufficient force or pressure} suddenly" force the bleaching or dyeing liquors. into and.tlirnughnyeryQmiuutepore. and fibreof the nlothsor fabrics... Bythismeens .the' nbleaching or dyeing is thoroughly accomplished in a few hours, and without endangering the strength of the fibre by long-continued action of the liquors, which often happens by'fqllowing theior'dinary modes. If the vessel or cylinder is stationary, suitable means should beemployed for an internal agitation of the contents, so that the result may be speedily accomplished and every part be operated upon equally and efi'ectually. This can be done, by a wheel or dashers fastened to a shaft and worked from the outside. Preferably a rotating or revolving; cylinder should be used, with brackets, pins, or arms fastened at intervals to the interior sides thereof, and projecting towards the centre, so that, as the cylinder revolves, the cloths and fabricsas'well as the dyeing and bleaching liquors will be constantly moved and agitated. Thisinternal movement and agitation is essential to the proper working of the process. Beneath or under the vessel or cylinder, a vat or tub is placed to'reoe ivc the liquors and the cloths or fabrics when the man-hole cover is removed. The liquors can be pumped out, strengthened, and used repeatedly. Whatsoever air may be in thecylinder will be compressed by the action pf the force-pump while injectingthe fluids, thus producing a combined action of'pneuma'tic and hydraulic or hydrodynamic pressure. By this process the most delicu'te fabrics ivill be unininrerhirom theforces usedocting equally and uniformly on all the parts thereof. In the ordinary. processes of bleaching, acids are required to destroy the afllnity existing between the chlorine and the lime, and to release the chlorine gas. By'the process above described, the chlorine is released by, the pressure and without acids, thus expediting the process, and lessening the expense. I I I We claim no particular form of apparatus or machinery. What we claim as'our invention, amhdesire to secure by Letters Patent, isi v I I The bleaching and dyeing of cloths, yarns, and other textile fabrics, by the combined or separateiuse of hydraulic or hydrodynamic and pneumatic pressure, in a closed vessel orcylinder, in combination with" rotary motion, or internal agitation or movement of the liquors, cloths, and fabrics, while under pressure, by the means.

' and substantially as above described.
